Graduate mathematics students will find this book an easy-to-follow, step-by-step guide to the subject. Rotman's book gives a treatment of homological algebra which approaches the subject in terms of its origins in algebraic topology. In this new edition the book has been updated and revised throughout and new material on sheaves and cup products has been added. The author has also included material about homotopical algebra, alias K-theory. Learning homological algebra is a two-stage affair. First, one must learn the language of Ext and Tor. Second, one must be able to compute these things with spectral sequences. Here is a work that combines the two.

印刷错误也太多了吧。。。
评分写的很详细,入门的好书。
评分印刷错误也太多了吧。。。
评分Rotman可谓某种程度上的咸鱼之友(褒义)。
评分前几天在朋友圈里看到一篇“1+1=2”来介绍category的,草草读了一下,就想起若干年前读过的这本书了。这本书好在确实把最好的东西都放进去了,不好之处在于堆了一大堆杂货,如果读这种厚书,学会切住最重要的东西可能是首要的。
